The makers of the film "What Happened on the Moon" participate in a round table with Jon Ronson in 1997 about the possibility of a moon landing hoax

Different Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Moon landingswere hoaxes staged by NASA and members of other organizations. Various groups and individuals have made such conspiracy claims since the end of the Apollo program in 1975. The most notable claim is that the six manned landings (1969–1972) were faked and that the Apollo astronauts did not walk on the Moon. The conspiracy theorists (henceforth conspiracists) argue that NASA and others knowingly misled the public into believing the landings happened by manufacturing, destroying, or tampering with evidence; including photos, telemetry tapes, transmissions, rock samples, and even some key witnesses.

There is much third-party evidence for Apollo Moon landings and detailed rebuttals to the hoax claims, including photos taken by more recent spacecraft of the moon landing sites. However, polls taken in various locations have shown that between 6% and 20% of Americans surveyed believe that the manned landings were faked, rising to 28% in Russia.
